D) -24.(-13+9)-35
E) (-3).(+7)-(-2).(-8)
F) 56-(-22).(+4)+144

Answer 1

D) -24 . (-13 + 9) - 35 = + 312 - 216 - 35 = 61

E) (-3).(+7)-(-2).(-8) = - 21 - (+16) = -37

F) 56 - (-88) +144 = 56 + 88 + 144 = 288

Answer 2

D)
= - 24.(- 13 + 9) - 35 
= - 24.( - 4) - 35
= 96 - 35
= 61

******************************
E)
= (-3).(+7) - (- 2).(- 8) 
=  - 21 + 2.(-8)
= - 21 - 16
= - 37

**********************************
F)
= 56 - (-22) .(+4) + 144
= 56 + 22.4 + 144
= 56 + 88 + 144
= 144 + 144
= 288
